Description

Technical Field

[0001] The utility model relates to an intelligent manual-automatic driving device for doors and windows. Background Art

[0002] With the continuous improvement of social living standards, the high demand for comfortable living has promoted the continuous development of intelligent buildings and residences. Smart door locks, electric curtains, automatic doors and windows, etc. have been widely promoted and applied. Common automatic doors, windows and curtains are only opened and closed electrically. They cannot be opened and closed manually when there is a power outage or the motor and control fail or when manual operation is required.

[0003] The utility model patent (authorization announcement number: CN210178797 U) proposes a solution based on the manual-automatic clutch of the movable planetary gear. The planetary gear rotates around the sun gear until it contacts or separates from the meshing member, realizing manual and automatic integration. However, after the planetary gear drives the meshing member, it is often difficult to disengage the manual due to the force meshing, so further improvement and perfection is needed. Summary of the invention

[0004] The purpose of the utility model is to provide a new manual-automatic drive device for intelligent doors and windows that can electrically control the opening and closing of door curtains or manually open and close door curtains according to scene requirements; it does not require any additional mechanism, and manual and automatic operations can be freely switched, which is more reliable.

[0005] The technical solution of the utility model is:

[0006] A new type of manual and automatic driving device for intelligent doors and windows, characterized in that: it comprises a front gear driven by a front driving mechanism, the front gear meshes with an eccentric gear sleeved on a rotating shaft, the rotating shaft is also sleeved with an eccentric gear sleeve and a clutch gear, the clutch gear meshes with a rear gear, and the rear gear outputs torque to drive a swing arm or a rack or a chain to open and close the door and window;

[0007] The upper end face of the yaw gear is provided with a boss, and inclined surfaces are provided on both sides of the boss and are symmetrically arranged relative to the center; the lower end face of the yaw gear sleeve is provided with two straight grooves and are symmetrically arranged relative to the center, and a magnetic column is provided above the center of the two straight grooves, and a steel ball I is provided in the two straight grooves, and the steel ball I is attracted by the magnetic column; the inclined surface of the boss on the upper end face of the yaw gear and the straight groove of the yaw gear sleeve are against each other, and the yaw gear sleeve and the clutch gear sleeve can rotate separately on the rotating shaft. When the yaw gear rotates and the yaw gear sleeve does not rotate relatively, the steel ball I is squeezed by the inclined surface of the boss on the upper end face of the yaw gear and can slide linearly along the straight groove in the yaw gear sleeve; the inner hole wall of the clutch gear is provided with an arc-shaped groove and is evenly distributed along the circumference. The arc radius of the arc-shaped groove is consistent with the radius of the steel ball I, and the arc bow height of the groove is approximately 1 / 2 of the arc radius, which can ensure that the steel ball I can smoothly disengage from the groove.

[0008] The lower part of the eccentric gear sleeve is installed in the gripping seat, and the gripping seat is symmetrically provided with a spring seat, a spring and a steel ball II. Under the action of the spring force, the steel ball II produces a certain clamping force on the lower outer circle of the eccentric gear sleeve. The eccentric gear sleeve can rotate around the rotating shaft and be slightly gripped by the steel ball II.

[0009] The utility model can electrically control the opening and closing of the door curtain according to the scene requirements, and can also manually open and close the door curtain; there is no need to add any additional mechanism, and manual and automatic operations can be switched freely.

[0015] A new type of manual and automatic drive device for intelligent doors and windows, the motor drives the front gear through a worm helical gear mechanism or a planetary gear, the front gear 01 meshes with the yaw gear 02 mounted on the rotating shaft 05, the rotating shaft 05 is also mounted with an yaw gear sleeve 06 and a clutch gear 03, the clutch gear 03 meshes with the rear gear 04, the rear gear 04 outputs torque to drive a swing arm or a rack or a chain to open and close the doors and windows.

[0016] The upper end surface of the yaw gear 02 is provided with a boss, and inclined surfaces are provided on both sides of the boss and are arranged symmetrically relative to the center; the lower end surface of the yaw gear sleeve 06 is provided with two straight grooves and are arranged symmetrically relative to the center, and a magnetic column 07 is provided above the center of the two straight grooves, and a 08 steel ball Ⅰ is provided in the two straight grooves, and the 08 steel ball Ⅰ is attracted by the magnetic column 07; the inclined surface of the boss on the upper end surface of the yaw gear 02 and the straight groove of the yaw gear sleeve 06 are offset, and the yaw gear sleeve 06 and the clutch gear 03 are mounted on the rotating shaft 0 5 can rotate separately. When the yaw gear 02 rotates and the yaw gear sleeve 06 does not rotate relatively, the 08 steel ball I is squeezed by the inclined surface of the boss on the upper end face of the yaw gear 02 and can slide linearly along the straight groove in the yaw gear sleeve 06; the inner hole wall of the clutch gear 03 is provided with arc grooves evenly distributed along the circumference, the arc radius of the groove is consistent with the radius of the 08 steel ball I, and the arc bow height of the groove is about 1 / 2 of the arc radius, which can ensure that the steel ball I can smoothly disengage from the groove.

[0017] The lower part of the yaw gear sleeve 06 is installed in the gripping seat 12, and the gripping seat 12 is symmetrically provided with a spring seat 09, a spring 10 and a steel ball II 11. The steel ball II 11 exerts a certain pressing force on the lower outer circle of the yaw gear sleeve 06 under the action of the spring force, and the yaw gear sleeve 06 can rotate around the rotating shaft 05 and be slightly gripped by the steel ball II 11. The gripping seat is fixed on the housing of the driving device (i.e., the housing surrounding the gears 01, 02, 03, 04).

[0018] When the motor is driven, the front gear 01 rotates, the yaw gear 02 meshes and rotates, and the yaw gear sleeve 06 does not rotate under the gripping force of the 11 steel ball Ⅱ. The inclined surface of the boss on the upper end face of the yaw gear 02 squeezes the 08 steel ball Ⅰ, causing the 08 steel ball Ⅰ to move outward along the straight groove on the yaw gear sleeve 06. At this time, the clutch gear 03 does not rotate. Since there are multiple arc-shaped grooves evenly arranged on the inner wall of the clutch gear 03, the 08 steel ball Ⅰ will quickly enter the arc-shaped groove of the clutch gear 03, so that the yaw gear sleeve 06 can clamp the clutch gear 03 and rotate coaxially. At the same time, the 08 steel ball Ⅰ is squeezed by the inclined surface of the boss of the yaw gear 02 to rotate together, and the clutch gear 03 and the yaw gear 02 achieve synchronous rotation. The clutch gear 03 meshes with the rear gear 04 for transmission until the final gear reduces speed and outputs a large torque. When the rotation stops at the set stroke, the gear 02 is reversed quickly. The inclined surface of the boss on the upper end of the yaw gear 02 is separated from the 08 steel ball I, and the extrusion force acting on the 08 steel ball I disappears. Under the action of the magnetic column 07, the 08 steel ball I is sucked into the center of the magnetic column along the straight groove on the lower end of the yaw gear sleeve 06. The 08 steel ball I is completely separated from the arc groove of the clutch gear 03, so that the yaw gear sleeve 06 and the clutch gear 03 are separated. The clutch gear 03 can rotate freely in both positive and negative directions, and the rear gear 04 meshing with the clutch gear 03 can also rotate freely. At this time, the manual operation function can be realized. Since the inclined surface of the boss on the upper end of the yaw gear 03 is arranged symmetrically with respect to the center, the meshing and separation of the clutch gear can be realized regardless of the positive and negative rotation of the motor.
